Application mea october is, 1922; serial no. 595,257.

One o1' thge objects of the lnventionis to permit and arrange 'for the movement of the brest roll for e('m venienee in applying a .new wire to the maehin'e: Another 'object of the/invention is to provide simple. praeti'al and easily operated means for securing such brest'roll movement. ln the accompanying drauingzs Fig. l is a side elevation of the brest .rollend of a l `ourdrnier machine having` means en'ibodyingr4 the invention for set-urineT movement-of Z5 the brest roll longitudinally of the-table:

Fig. .2 is a sideelefvation of such table end with the brest roll adJusted:

Fig. 3 is a eross'seetion taken on line 3-3 in Fig. 2. Y

Referring-.to tbe draung's, l show 'an end portion of a `l `ourdringier finaehine comprisinn` tableside members'1--1, preferably in the' form of channel bars, as *best shown in .Fign Table-rolls 2*2 are mounted on the 'table by means` of brackets 3 3 Supported on and bolted to the upper member 1 ofthe channel members 141'.A T liebraekets 3`-3 extend beyond 'the ends of thefside 'channel bars 1-1. as bestfshoivn in Fig. 2. The wire I .40 5 is shown extended over tbe table rolls 2---2V The brest roll 6'. is shown mounteden 'a sliding frame'or carriage conveniently coinosed Aof tuo sliding meinbers-'e'prefervably in the torni of vchannel bars fitting into ing saddlelike ends S-S supporting bear- 1 ings 9?-9 for the brest roll axle 10. Said saddlesv 8-8 .are provided with vprojections or'h'eoli members 11 to engage cables 12 to 450 support the end of the' table',;to permit the.

table' to; be elevated slightlyend then moved out for pplyng a lnew wire in the fornrof e continuous or .endless band.

'lThe shaft 18 of Wheel 15 has a pinion 19 meshing; with a 'gearQ'O On'a Cross shaft 21 -Whieh'extends erossu'ise of the table 65 from side to side'thereof, as shown injFig. 3. 4 Said sbat 217 is provided with pinions 22e-22 at or vnear its opposite'ends and these pinions 22 mesh with raeks 23 on the upper 'langes of members 7-7. Thus 4 rotation of" 70 the lwheel 15 will cause movement Aof the brest roll frame in onedireetion or the other`r and thereby more the .brest roll G toward angl aufay from the main body portion o' the ta le.

For holding the` members 7--7 in position in the table sides 1 -1 l sbou'lbolts 24--25.

- ,and 4also show the members 7-7- provided with elongated slots 26' in which said bolts;

are located. The slots 26- are large enough' to 80 l accommodate the cross shaft 21. so that, the members T7 may slidei relativelyito said shaft. Endportions' 27 of the slots 26ers reduced in size. however, soas to aeeommodate vonly bolts 2 4'. the reduction of the 85 size et slots 26 'limitingthe extentof inward movement on the part' of the sliding frame,

(Fig. v2), the' outward movement of the same shown in Fig. 1. Y

In Fig, 1 lthe lmachine is shown in operat-l ing condition with the-table rolls 2 in'posi tion and the brest. roll 6 in its outermost position by reason of the outward projection of l its-adjustable frame. In Fig. 2 thebrest roll- 95 isshown adjusted inwardly as far as possible' 'by its adjustable carriage.v to'p'ermit. which threeof thetable rolls 2 lia've'been removed'4 from their bearings, this being necessary to per-mit the inward'movement of thel brest ma roll (i.A Such removed table rolls may., for convenience, lbe placed on top of'otherl Vtable rolls, as shown in dotted lines in Fig,
